JCVLenepveu
For me he never was a "Boussaroque de Laffont" - His brother René (Charles Fredéric Hyacinthe René)Probably changed his name and his son's in 1850 (date of the request for a new name for his son, 5 years old then)
He had got 2 other siblings: Aimée and Prosper Lenepveu (my great/great/grandfather).
